Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Theophylline competitively inhibits phosphodiesterase, increasing cAMP levels, and acts as an adenosine receptor antagonist, leading to bronchodilation and reduced airway inflammation.
Theophylline is a xanthine derivative that acts as a competitive nonselective phosphodiesterase inhibitor, increasing intracellular cyclic AMP levels, and as an antagonist at adenosine receptors (A1 and A2 subtypes), leading to bronchodilation, anti-inflammatory effects, and stimulation of respiratory drive.
For asthma and COPD: 1-2 inhalations (90 mcg each) via metered-dose inhaler, 2 puffs twice daily, maximum 4 puffs twice daily. For acute exacerbations: 4-8 puffs every 20 minutes for up to 4 hours, then every 1-4 hours as needed.
Oral: 200-400 mg every 6 hours (maximum 1600 mg/day) as sustained-release tablets or liquid. Inhalation: Not applicable.

Terminal elimination half-life 12 hours; clinical context: q12h dosing achieves steady-state in 2-3 days
Terminal elimination half-life is 3–5 hours in adults (nonsmokers), but prolonged to 6–8 hours in neonates, elderly, and patients with hepatic cirrhosis or heart failure. Smoking (tobacco or marijuana) reduces half-life to 1–2 hours due to enzyme induction.
Renal (80% as unchanged drug), biliary/fecal (15% as metabolites), 5% other
Renal excretion of unchanged drug accounts for approximately 10% of elimination; the remainder is hepatically metabolized, with 80% excreted in urine as metabolites (1-methyluric acid and 3-methylxanthine) and less than 10% in feces.
